Configuring Triggers for Jitter Violations
Jitter values are computed as source-to-destination and destination-to-source values. Events, for example,
traps, can be triggered when the jitter value in either direction or both directions rises above a specified
threshold or falls below a specified threshold. You can configure jitter-average as a monitored element.

DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Configures certain actions that are based on events under the
control of the IP SLA agent. The operation-number argument
ipsla reaction operation operation-number
Example:
RP/0/RSP0/CPU0:router(config)# ipsla reaction
operation 432
Step 2
is the number of the IP SLA operations for the reactions that
are configured. The range is from 1 to 2048.
Specifies an element to be monitored for a reaction.react [jitter-average {dest-to-source | source-to-dest}]
Step 3
Example:
RP/0/RSP0/CPU0:router(config-ipsla-react)# react
A reaction occurs if the average round-trip jitter value violates
the upper threshold or lower threshold. The following options
are listed for the jitter-average keyword:
jitter-average
• dest-to-source—Specifies the jitter average destination
to source (DS).
RP/0/RSP0/CPU0:router(config-ipsla-react-cond)#
• source-to-dest—Specifies the jitter average source to
destination (SD).

Step 4
Configuring Triggers for Packet Loss Violations
Packet-loss values are computed as source-to-destination and destination-to-source values. Events, for example,
traps, can be triggered when the packet-loss values in either direction rise above a specified threshold or fall
below a specified threshold. Perform this task to configure packet-loss as a monitored element.
